BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to support structures for the walls and decking that define an inground swimming pool.

2. Description of the Related Art

Construction of an inground swimming pool involves excavating the land area where the swimming pool is to be located. Typically, the excavation extends for about 2-3 feet beyond the outer dimensions of where the pool's walls will be fixed in place. Once the hole is dug, the walls that provide the structural rigidity and shape to the pool are set in position and interconnected to one another. As shown in FIG. 1, an A-Frame brace is then set against the exterior surface of each wall to maintain the walls plumb. A concrete bond beam is poured along the exterior base of the pool walls and bottom leg of the braces to provide a locking collar to prevent the walls from collapsing after water fills (and creates pressure against the walls of) the pool.

After the concrete has hardened, the ditch that exists between the undisturbed earth and the exterior surface of the pool walls is back filled with dirt from the excavated hole while the pool is filled with water. Once the fill has settled, a 4-6 inch thick by 3-4 feet wide concrete deck is installed around the exterior perimeter of the pool. If the decking is poured prior to the backfill being fully settled, cracking and breaking of the concrete deck will likely occur causing the deck to slip inwardly towards the pool, potentially causing the pool's walls to shift and eventually leading to significant repairs being required to maintain the pool.

It is a principal object and advantage of the present invention to provide a support structure for concrete decking that permits the decking to be poured regardless of whether the back fill has settled.

It is another object and advantage of the present invention to provide support structure for concrete decking that is adjustable to accommodate pool walls of varying heights.

It is a further object and advantage of the present invention to provide support structure for concrete decking that may be used with straight or curved pool walls and with walls composed of different materials.

Other objects and advantages of the present invention will in part be obvious and in part appear hereinafter.

SUMMARY OF THE INVENTION

In accordance with the foregoing objects and advantages, the present invention provides a pool wall and deck support member comprising modular and symmetrical upper and lower halves adapted to be interconnected to one another to form the unitary support member. Each half is essentially V-shaped with the bottom of the V having a pair of fastening elements disposed thereon and adapted to securely engage corresponding fastening elements disposed on the bottom of the V of the opposite half. Disposed on the ends of the upwardly extending legs of the V-shaped members are fastening elements that are adapted to engage a cross bar that extends across the V-shaped member. While each half of the V-shaped members are approximately equal to half the height of a standard pool wall (e.g., about 21 inches each), extension modules having correspondingly shaped and positioned fastener elements disposed on opposing sides thereof may be disposed and interconnected between the two halves to increase their height to accommodate walls of varying heights. The modules can be of whatever thickness (or height) is necessary, and several extension modules can be interconnected between the two halves to satisfy the height requirement.

Cross bars are connected across both the top and bottom of the support module (the top cross bar extending across the top of the upper V-shaped member and the bottom cross bar extending across the bottom of the upside down oriented V-shaped module). Each cross bar includes a flange that may be fastened to the pool walls, or to the splines of the pool walls so as to interconnect the support structure to the pool walls. The attachment mechanism is adjustable in dimension to ensure that the support member can be connected to the wall in a manner that establishes and maintains the wall plumb in an essentially vertical plane. In addition to the attachment mechanism, a series of clips having rebar support yokes are placed over the top cross bar.

Once the series of assembled support members are fastened to the pool walls, a concrete bond beam of approximately 8 inch thickness may be poured in the ditch between the undisturbed earth and the bottom of the pool walls. Once hardened, the concrete bond beam will secure the support member is position relative to the pool walls.

Back fill may then be used to fill in the space above the concrete bond beam and the remainder of the excavated site between the undisturbed earth and pool walls. Once backfilled (or prior to backfilling if desired), steel rebars may be extended between adjacent support members, with each length of rebar seated in the yokes that are positioned atop each upper cross bar. Once the rebars are in place a concrete deck may be poured over the top of the backfill. The steel rebars will be encapsulated within the concrete deck and the weight of the deck will be fully supported by the support members, with each section of decking extending between two adjacent support members.

DETAILED DESCRIPTION

Reference being had to the drawings, wherein like reference numerals refer to like parts throughout, there is seen in FIG. 3. among others, a generally X-shaped pool wall and deck support member, designated generally by reference numeral 10, comprising modular and symmetrical, upper and lower V-shaped elements 12, 14, respectively, interconnected to one another at their respective vertices to form the X-shaped support member 10. With reference to FIGS. 3, 5 and 6, one or more extension modules 16 may be interconnected between the V-shaped elements 12 and 14 to extend the height of the support member 10 and accommodate pool walls of varying heights. Support member 10 further comprises upper and lower cross members 18 and 20, respectively, which extend in a common plane with support member 10 and between the terminal ends of the upper and lower elements 12 and 14, respectively.

Each element 12 and 14 includes a male and female connector/fastening element 22, 24, respectively, formed on each element's vertex, as well as a pair of male connectors/fastening elements 26, 28 formed on the end of each leg. In assembling support member 10, the male connector 22 of one element 12 is securely engaged with the female connector 24 on the opposing element 14, and the female connector 24 of one element 12 is securely engaged with the male connector 22 with the opposing element 12. Each extension module 16 includes male and female connectors 30, 32 formed on each of its edges, which are positioned for secure engagement with corresponding female and male connectors 24, 22, respectively, when extension modules are used for increasing the height of support module 10.

The cross members 18 and 20 each include a plurality of longitudinally spaced apart, slotted openings 34 formed therethrough, and connecting members 36 extending longitudinally outwardly from the cross members. Each cross member is affixed to element 12 or 14 by securely inserting male connectors 26, 28 through correspondingly positioned openings 34. As an alternate accessory, clips 38 may be securely placed over the top of upper cross member 18. Each clip 38 includes a yoke 40 extending upwardly therefrom that is adapted to have a length of steel rebar seated therein for purposes that will be described hereinafter.

Connecting mechanisms 36 interact with an upper attachment mechanism 42 to interconnect the top cross member 18 to pool wall 15 and with a lower attachment mechanism 44 to interconnect cross bar 20 to pool wall. Upper attachment mechanism 42 includes a pair of adjustment angles 46, 48 interconnected by a bolt 47 and nuts 48, and a pair of bolts 50, 52 (nutted on each end) that pass through legs of angles 46, 48. By threading bolt 47 to vary the distance between angles 46 and 48, the pool wall can be established and maintained plumb (e.g., set in a vertical plane).

Lower attachment mechanism 44 simply comprises a plate 54 that is interconnected with bolts/nuts 56 between pool wall 15 and connecting mechanism 36.

With reference to FIGS. 11-13, when attaching support member to a pool wall having a radius, an attachment bar 58 and attachment clip 60 are utilized. Clip 60 includes a first U-shaped region 62 adapted to securely engage the wall's upper edge, and a second U-shaped region 64 co-linear with and adjacent to the first region 62 that is adapted to securely engage over the top end of attachment bar 58. Attachment bar 58 is vertically oriented to stand adjacent to the wall and is fastened to clip 44 via screws that pass through both the clip 60 and the bar 58. Support member 10 is then fastened to attachment bar 58 using attachment mechanisms 42 and 44.

Once support member 10 is firmly in place relative to pool wall 15, concrete is poured in the bottom of the trench between the undisturbed earth and pool wall 15 to form a concrete bond beam 66. Once hardened, the concrete bond beam 66 will secure the support member 10 in position relative to the pool walls 15.

Back fill may then be used to fill in the space above the concrete bond beam 66 and the remainder of the excavated site between the undisturbed earth and pool walls 15. Once backfilled (or prior to backfilling if desired), steel rebars 68 may be extended between adjacent support members 10, with each length of rebar seated in the yokes 40 that are positioned atop each upper cross bar 18. Once the rebars 68 are in place a concrete deck 70 may be poured over the top of the backfill. The steel rebars 68 will be encapsulated within the concrete deck 70 and the weight of the deck 70 will be fully supported by the support members 10, with each section of decking 70 extending between two adjacent support members 10.
